openocd是怎么获取到外部qspi-flash的信息的？我按照步骤修改好了stm32h7x.cfg文件，用telnet打开openocd创建的端口查询当前的flash列表，列表有qspi-flash，但是查询信息出错。

[C] 纯文本查看 复制代码

Open On-Chip Debugger

另外，我用的是h750vb，qspi挂载在bank2，目前驱动正常能读写。

关于makefile和openocd这两个东西，你们都是从哪里找到玩法的？
我从百度上搜索，都是一些零零散散的资料。

现在只会简单的修改，但是不清楚这两个东西的原理是什么。自己想改的复杂一点去哪里可以学？

VSCODE，这些都支持。除了一个会自动覆盖内容的bug，其他都挺好。

记录一下使用mingw32+makefile命令行+daplink+openocd的方式烧录h750外部qspi-flash的后续：

1.目前openocd最新的版本（0.11.0 (2021-11-18)）已经对st的qspi有了很好的支持，具体可以看官方github上的stmqpsi.c的实现，并配合stm32h750b-disco.cfg和stm32h7x_dual_qspi.cfg这两个文件来看。
[https://github.com/sysprogs/openocd]附上我编改的.cfg配置文件

stm32h7x.cfg (9.55 KB, 下载次数: 8)

stm32h7x_qspi.cfg (5.88 KB, 下载次数: 11)

2.在stm32h7x_qspi.cfg中重点实现了io映射初始化和qpsi初始化，这部分配置要确保无误。

3.openocd的烧录命令可参考网上的一些方法，这里放出我在makefile上的命令作参考：

[C] 纯文本查看 复制代码

OCD_EXE = ./tools/OpenOCD/bin/openocd.exe
OCD_INF = ./tools/OpenOCD/scripts/interface/cmsis-dap.cfg
OCD_TARGET = ./tools/OpenOCD/scripts/target/stm32h7x.cfg
OCD_TARGET_QSPI = ./tools/OpenOCD/scripts/target/stm32h7x_qspi.cfg

flash:
	$(OCD_EXE) -f $(OCD_INF) -c "transport select swd" -f $(OCD_TARGET) -c init -c halt -c "flash write_image erase $(FLASH_HEX)" -c reset -c shutdown
#	$(OCD_EXE) -f $(OCD_INF) -c "transport select swd" -f $(OCD_TARGET) -c "init; halt; flash write_image erase $(FLASH_HEX); reset; shutdown;"

flash-qspi:
	$(OCD_EXE) -f $(OCD_TARGET_QSPI) -c "init; reset init; halt;" -c "flash write_image erase ./testbin.bin 0x90000000" -c reset -c shutdown

4.实现原理：命令openocd.exe -f $(CFG)启动openocd后，再输入命令“reset init”即可启动stm32h7x_qspi.cfg文件中的初始化代码，从而MCU相应的外设得到了初始化，随后openocd调用自身的stmqspi部分代码进行flash的擦除与写入。

我靠！大佬！一开始我也遇到读不了flash信息的问题，不过后来我貌似是通过修改qspi部分的代码解决的。
